Ottjes, J.A. (author)
A model is derived to calculate the pressure losses originating from the dilute phase pneumatic transport of coarse particles in the horizontal stationary flow regime. The model is based on the balance of drag forces and frictional forces acting on the particles during pneumatic transport. The particles are characterized by the particle terminal...

The interaction of a gravity wave with a steady uniform current is discussed in this paper. Analysis indicates there is no dominant difference in the results obtained when employing either the equation of conservation of wave energy flux or the equation of conservation of wave action flux. Numerical calculations of the wave length change by...

Booij, N. (author)
A mathematical model for the combined refraction-diffraction of linear periodic gravity waves on water is developed, in which the influence of inhomogeneities of depth and current is taken into account. The model is used to compute partial reflection of waves a gully or an undersea slope, with influence of a current. The model is also applied to...

Three-dimensional glancing-shock/turbulent boundary-layer interaction has been investigated at the Cranfield Institute of Technology in two separate test programmes using a 2.5 x 2.5 inch intermittent tunnel and a 9 x 9 inch inch continuous tunnel, at a Mach number of approximately 2.5. The experimental results include oil-flow pictures, vapour...

For the effective performance of its work, the Rijkswaterstaat, which has a staff of about 12.000, consists of 25 Directorates with different duties. One of them is the Meetkundige Dienst (Survey Department) with a staff of about 500, which is charged with the geodetic support of the Rijkswaterstaat. Part of this support is the preparation of...

Kooi, J.W. (author)
An experiment is described in which a nominal normal shock impinges on a turbulent flat plate boundary layer. The wall pressure distribution in the interaction region was measured for Mach numbers in front of the shock of 1.40, 1.44 and 1.46. The Reynolds number based on shock position was 18 X 10(6) and based on momentum thickness at the start...

Vlieger, H. (author)
Past experience has shown that during the operational life of an aircraft structure cracks or failures may arise in different structural components. In future designs the designer must be able on the one hand to restrict the occurrence of cracks by a careful detail design and on the other hand to guarantee some specified life of the aircraft if...

Series of measurements with irregular waves were undertaken for model seawalls of vertical walls with and without protection by concrete block mounds. Experimental data were compared and supplemented with theoretical calculations by the combination of the author's random wave breaking model in shallow waters and the weir type overflow model. The...

Snel, H. (author)
A model is derived for the calculation of the properties of a jet exhausting into a non-uniform main flow, at an arbitrary angle to the initial jet direction. The model is a generalisation of an earlier jet-ina-main flow model for uniform main flows. Semi empirical input is limited to an entrainment relation and a relation for form factors of...

Snel, H. (author)
A novel method is presented for the calculation of the flow field induced by a turbulent jet exhausting into a uniform cross flow. Outside the jet boimdary, potential flow is assumed. The jet effects are represented by a source distribution on the jet boundary. The boundary conditions on the jet boundary (normal velocity) are calculated from a...

Bijker, E.W. (author)
11th Conference on Coastal Engineering in London 1968, the author presented a method for computing the littoral drift starting from the longshore current velocity as this is generated by the waves and with the assumption that the material is stirred up by the waves. In this paper measurements in a model basin are described by which the procedure...

Ferguson, H.A. (author)
The hydraulic model is playing an increasing part in the process of hydraulic designing and it seems even to have taken over the dominant position that experience and tradition had held for such a long time. But, however important the model tests have become, they are not the only means available to the designer, nor does he have to rely solely...

This paper deals with model tests conducted at the Delft Hydraulics Laboratory (DHL) and the River and Harbour Laboratory at the Technical University of Norway (RHL) for the design of the Europoort Breakwater. A series of tests with regular waves was conducted at the DHL from which the design of the breakwater was decided. The chosen design was...

At the inauguration of two advanced wind-wave flumes in the Netherlands, three decades after BAGNOLD's pioneer work, and one decade after the Haringvliet sluice investigation and the joint Dutch-Danish investigation of the Hanstholm breakwaters, it seems appropriate to summarize current knowledge on wave shock phenomena. These may be classified...

It is described why, and to what extent the practicing engineer makes use of model tests in his design of rubble mound breakwaters. Furthermore an example is shown from practice illustrating the application of models for investigation of wave penetration into harbours. Especially the way in which model tests can confirm and supplement...

This memorandum proposes a mathematical approach of the interactions between a non-viscous fluid with a free surface and an assembly of structures composed of shells, whether fixed or not, partially or totally immersed in the fluid. Some fundamental aspects of the problem, such as the effects of the free surface and of the mutual influence of...
